tion are to provide a strong rigid st-ructurewhich can be manufactured at a low cost, .will possess great strength and rigidity and the respective parts of which can be readilyV and easily assembled, and the parts of which are maintained and locked in theirassem-l bled positions without makinguse of any screws, bolts, rivets or other similar appliances.

In the accompanying drawings I have shown the preferred embodiment of my invention in whioh Figure 1 shows an elevation of a cabinet section or unit constructed inv accordance with my invention. Fig. 2 is a sectional ele-- vation of a cabinet section or-unit embodying my invention. Fig. 3 is a sectional view on the line 3 3 of Fig. .1.. Fig. 4 is an elevation partly in section .of the outer shell or frame of the structure shown in Fig. 1. Fig. 5 is a section on the line 5 5 of Fig. 4. Fig. 6 is a plan view of the back plate or wall of the structure shown in Fig. 1. Fig. 7 is a sectional view on the linef7 7 of Fig. 6. Fig. 8' is a plan view of one of the interior walls of thestructure shown in Fig. l. Fig. 9 isa sectionon the line 9 9 of Fig. 8. Fig. 10 is a plan view of the inner back section of the structure shown in Fig. l. Fig. 11 is a sectional view on the line 11 11 of Fig. 10.

Similar figures of reference refer to similar parts .throughout the several views.

The preferred embodiment of my invention as shown in the accompanying drawings consists of` a frame 1 of sheet metal, preferably steel, which is rectilinear in form, and the four sides of which form four of the exterior walls of the cabinet section, namely the upper and lower outer walls and the two outer slde walls of the section. This frame-work is also provided with flanges 2 and 3 which are turned inwardly at right angles to the walls of the frame and these flanges 2 and 3Mare provided" with inwardly turned flanges 4 and 5 which as Shown are projected substantially parallel to the side walls` of the frame. This frame may be struck up from a single piece of metal or may be bent into shape and joined together as shown in Fig. 4 byover-turning the adjacent edges and securing them together by the clasp 6 or they may be welded or secured ytogether in any other suitable manner.

The outer backI or rear wall member as shown in Fig. 6 consists of a metallic plate 7 which is notched at the corners and is formed into a .pan shape with flanges 8 as shown in Fig. 7. The back 7, which is a driving fit is then forced into the frame in the position shown in Fig. 3 and is retained in that position by frictional Contact between the inwardly turned' flanges 5 and the' flanges 8 of the back 7. v

As illustrated the preferred embodiment of my invention shows a structure with doulole walls'. -members 9 9 are provided with rectangular flanges 10-10 and double angular lflanges 11-'11 and are adapted yto be forced into the posit-ion shown in Flg. 3, that is with thel double angular flange interlocked under and back of the flange 4 on the frame, and the flange l() forced in over the fia-nge 8 into the position shown in Fig. 3 in which position it will'be firmly held by frictional Contact. The inner side wall members .l2-J2 are formed in the same manner as the upper and lower interior wall members 9 9 and are secured in position in the samemanner.

The upper and lower inner wall it has been forced into the position shown 'in Figl 3 A is securely locked in that position by means of lugs or` catches 14 which are secured to or formed in the face of' the `members9 9 and 12-12. The backwall member 13 is the locking member which s ecures all of the other members in position 1n the frame so that none Aof them can be re- .moved without .first removing the member cause the members and the frame being clesticv and the members and the frame .being all under tension When thel members are in position in the frame the parts adjust themselves to slight variations in the dimensions of the members or the frame thereby l `.avoiding the necessity of accurately fitting titl frame of sheet metal, interlocking danges on titi,

the members to each other and the frame,

and the members are locked in position` in the frame instead of being secured thereto by rivets, bolts or like mechanisms and because the trame and all of the members lare under `tension the structure when assembled is exceedingly rigid and any strains to Which it may be subJected will be distributed througlfxoiitl the entire structure. l have also found in'practice that the partscan be l assembled by unskilled labor and at a very 10W cost. 'lhis structure is also particularly adapted for tire proof cabinets and safes and possesses many advantages over similar structures in Which the parts are riveted or bolted together because when subjected .to heat there are no rivets or bolts to be sheared bythe expansion of the metal.

aving described my invention what l claim as new and desire to secure by Letters Patent is 1.
